Worst medical-type company I've ever dealt with, and that's saying a lot since I spent my entire career in the medical industry! Some of the highlights: They've refused to supply me (the customer) with billing statements to show what they've billed to my insurance...and EOBs from my insurance company reveal lots of charges for cpap supplies that were never ordered or received...that's billing fraud! Six months in and I've still not been measured a single time in order to find a mask that actually fits! They won't return my calls, won't respond to emails, etc! WORST COMPANY EVER (at least in the Alamosa, CO area)...AVOID!!!
